REVNETGROUP(8)		     NIS Reference Manual		REVNETGROUP(8)

NAME
       revnetgroup - generate reverse netgroup data

SYNOPSIS
       /usr/lib/yp/revnetgroup [-u | -h]

DESCRIPTION
       Revnetgroup processes the standard input in netgroup(5) format into
       what is called reverse netgroup form. That is, where the original file
       shows netgroup memberships in terms of which members reside in a
       particular group, the reverse netgroup format specifies what groups are
       associated with a particular member. This information is used to
       generate the netgroup.byuser and netgroup.byhosts NIS maps. These
       reverse netgroup maps are used to help speed up netgroup lookups,
       particularly for the innetgr() library function.

       The revnetgroup command prints its results on the standard output. It
       is usually called only by /var/yp/Makefile when rebuilding the NIS
       netgroup maps.

OPTIONS
       -u
	   Generate netgroup.byuser output; only username information in the
	   original netgroup file is processed.

       -h
	   Generate netgroup.byhost output; only hostname information in the
	   original netgroup file is processed.

FILES
       /var/yp/Makefile
	   The Makefile to build the NIS databases.

       /etc/netgroup
	   The default netgroup database file. This file is most often found
	   only on the NIS master server.

SEE ALSO
       getnetgrent(3), netgroup(5),
